The Ministry of Environmental Protection's standard "Technical Requirements and Inspection Methods for Portable Ultraviolet Absorption Measurement Instruments for Fixed Pollution Source Smoke (Sulfur Dioxide and Nitrogen Oxide) HJ1045-2019" was officially released on October 24, 2019. The release of this method provides a technical standard basis for the on-site application of portable ultraviolet differential smoke analyzers. With the national standard method standardThe release of the standard GB/T 37186-2018 "Gas analysis - Determination of sulfur dioxide and nitrogen oxides - Ultraviolet differential absorption spectroscopic analysis" and the release of the HJ1045-2019 instrument standard willThis is conducive to the standardization of the portable ultraviolet differential flue gas analyzer market and has led to the wider application of ultraviolet flue gas analyzers.      The ultraviolet differential flue gas analyzer is a new product with ultraviolet differential absorption spectroscopy technology as its core. The instrument * meets the requirements ofHJ1045-2019Technical requirements and inspection method standards for portable ultraviolet absorption measuring instruments for fixed pollution source flue gas (sulfur dioxide and nitrogen oxides). Mainly used for measuring harmful gas components in exhaust pipes, widely used in environmental monitoring and thermal parameter measurement departments,  This analyzer is a high-tech instrument with independent intellectual property rights that our company has carefully developed over the years. The product has obtained multiple proprietary technologies from China（201822059302.2 201822059303.7 201821768129.7),Software copyright (registration number):2019SR0068850)Technological innovation safeguards the product, which uses an industrial grade high-speed processor,10.1Inch industrial touch screen, human-machine interface compatible with button and touch dual modes, capable of networking and data transmission for local area network and wide area network; Three in one flue gas sampling, working condition measurement, and flue gas pretreatment, convenient for on-site use; Built in rechargeable lithium battery, dual-use for AC and DC, wide input voltage(DC 12~28 V,AC 80~260V),The voltage has a wider range of applications; Design of dual range sampling for smoke measurement and mathematical model correction algorithm to improve the accuracy and linearity of data measurement; The key components are controlled by constant temperature to increase the temperature range of the instrument.
